Abstract [en]

The report aims to identify new technologies for energy harvesting and the ability to use them in the road and the surrounding road area. The survey focuses on the materials and methods that may be used in the Swedish (cold) climate. The report can be useful for planning of new infrastructure when you want to make use of renewable energy and wants to reduce the environmental impact. Considering today’s technological conditions, the following techniques may be relevant: photovoltaics, geothermal energy, piezoelectric technology, wind energy or bioenergy. There are, however, many factors holding back the development of new innovative systems for energy production in roads and their environment. Some important factors are for example that maintenance costs will increase or that the maintenance of the road will become more difficult.
